Vorschrift

To a solution of 3-{[tert-butyl(dimethyl)silyl]oxy}-2,2-dimethylpropan-1-ol (Registry No. 117932-70-4) (2.18 g, 10 mmol) in THF (30 ml) were added triethylamine (1.67 ml, 12 mmol) and methanesulfonyl chloride (0.85 ml, 11 mmol) under ice cooling. The reaction liquid was stirred at room temperature for 30 minutes, and to the reaction liquid was added an aqueous solution of sodium bicarbonate. The mixture was extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous magnesium sulfate and concentrated under reduced pressure to give the title compound (2.98 g, quant.) as colorless oily substance.
